We are building a modified CNC machine that sprays paint instead of running a cutting blade. Because of this we need about 50 outputs to control different colors of paint. Can anyone recommend hardware (breakout boards, PLCs, modbus) which could do this? If I understand correctly, Mach 3 can support up to 63 outputs, right?

We have purchased the Homann ModIO, and I am aware that we can buy several of these and link them together to achieve our result. It would be great if we could do it in one unit though.

I'm a newcomer to CNC, so sorry if this is an obvious question.

Hey there...

Sorry for the late reply...
Do you still need more output hardware for your Project?
Maybe i have a good solution...

Kind Regards...
